Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating evaporation device for various kinds of chemical solutions, such as mosquito-killing chemical solutions, which are used by heating and evaporating them.

2. Description of the Related Art Conventionally, this type of heating evaporation device was developed, for example, by
A device having a configuration as shown in Japanese Patent No. 5876 is known. This example is shown in FIG. 3. Numeral 10 is a liquid medicine container for storing liquid medicine, and numeral 11 is a suction wick which is immersed in the liquid medicine and whose upper end extends above the main body case. (2) A heating element, which uses a ring-shaped positive temperature coefficient thermistor, is located around the upper end of the suction core 11. A switch 13 serves as a power switch for the heating element 12. A neon lamp 14 is housed in the switch 13 and can be turned on and off by turning the switch 13 on and off. 15 is a bottom case, and 16 is a main body case. The main body case 16 is engaged with the bottom case 15 to constitute the main body of the heating evaporation device. 17 is a slit, main case 1
6, so that the remaining amount of chemical solution can be seen from the outside.

In the above-mentioned conventional heating evaporation device, when the power switch 13 is turned on, the heating element 12 generates heat, and the suction core 1
The chemical liquid sucked up by 1 is heated and evaporated.

In addition, the medicinal solution is contained in the medicinal solution container IO, and the suction wick 11
is immersed at the lower end, so when switch I3 is turned on, the heating element! 2, the upper end of the suction wick II is heated,
Transpiration can begin immediately.

Furthermore, since the heating element 12 uses a positive temperature coefficient thermistor, the heating element 12 is highly safe because it does not heat up to a certain temperature or higher.

Problems to be Solved by the Invention However, in the heating evaporation device described above, the remaining amount of the chemical liquid in the chemical liquid container 10 is checked from the outside through a slit 17 provided in the main body case. It cannot be confirmed accurately unless your eyes are level with the liquid surface. In addition, since the inside of the chemical solution container 10 is dark, it is difficult to see the position of the chemical solution surface, making it easy to misread it, and there are problems in that it cannot be confirmed at all in a dark place.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a heating evaporation device that can easily and accurately check the remaining amount of a chemical solution in a chemical container even in a dark place.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has the following objectives: A chemical liquid in a transparent or translucent chemical liquid container housed in a heating evaporation device main body formed by engaging a main body case and a bottom case. In the heating transpiration device, the main body case is provided with a slit, and the bottom case is provided with a lamp and a transparent plate. A heating evaporation device was prepared in which the chemical solution container was placed on this transparent plate.

In addition, the heating evaporation device has a switch for blinking the lamp and a power switch for the heating element connected to each other in the same manner or in conjunction with each other.

Function As described above, in the present invention, a slit is provided in the main case, a lamp and a transparent plate are provided in the bottom case, and the chemical liquid container is placed on this transparent plate, so that the light from the lamp is transmitted through the transparent plate to the chemical liquid container. The light enters the chemical solution from the bottom surface of the device, and light is scattered at the interface of the chemical solution, making the interface illuminated, and the interface of the emitted chemical solution can be confirmed through the slit.

In addition, if the blinking switch of the lamp and the power switch of the heating element are made the same or linked, the lamp can be lit at the same time as the heating element is heated≧Example 1 of the present invention A heating evaporation device as an example will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a transparent drug solution container, which stores a transparent drug solution inside. Reference numeral 2 denotes a suction rod, which is immersed in the chemical solution and whose upper end extends upward from the main case. A heating element 3 is a heating element using an electric heater and a ring-shaped positive temperature coefficient thermistor, and is located around the upper end of the suction wick 2. A switch 4 serves as a power switch for the heating element 3. Reference numeral 5 denotes a lamp, which is a neon lamp and is connected to the switch 4, which is the same as the power switch 4 for the heating element 3. 6 is a bottom case, and 7 is a main body case, which is engaged with the bottom case 61 and constitutes the main body of the heating transpiration device. A slit 8 is provided on the side surface of the main body case 7 so that the remaining chemical solution can be seen from the outside through the slit 8. Reference numeral 9 denotes a transparent plate, which is provided on the bottom case 6, and the drug solution container 1 is placed on this transparent plate 9.
will be posted.

Next, the operation of this embodiment will be explained. When the switch 4 is turned on, the heating element 3 generates heat, and the chemical liquid sucked up by the suction wick 2 from the chemical liquid container l is thermally evaporated in this part, killing mosquitoes flying indoors.

In addition, when the switch 4 is turned on, the lamp 5 lights up, and this light passes through the transparent plate 9 and the bottom of the drug solution container 1 into the drug solution, makes the interface of the drug solution shine by light scattering, and is transmitted through the slit 8 provided in the main body case 7. The remaining amount of chemical solution can be easily and accurately confirmed.

FIG. 2 is an enlarged sectional view showing the vicinity of the interface of the chemical liquid. Due to surface tension, the liquid level of the chemical solution rises along the inner wall of the container at the contact surface with the container, as shown in a in the figure. For this reason, the light is refracted in a manner similar to that of the other portions, causing light scattering, thereby making it easier to confirm the interface.

In the above description, an example is shown in which the chemical liquid container l and the chemical liquid are transparent, but each may be semi-transparent.

Moreover, although the power switch of the heating element 4 and the switch of the neon lamp are made the same, they may be made to be able to operate independently.

Effects of the Invention In the present invention, as described above, the main case is provided with a slit, the bottom case is provided with a lamp and a transparent plate, and the chemical liquid container is placed on this transparent plate, so that the interface of the chemical liquid can be seen from the outside through the slit. Luminescence can be easily confirmed.

Therefore, the user does not need to check with his/her eyes level with the liquid level as in the past, and the interface of the chemical liquid is clearly shown by light scattering even in a dark place, making it possible to accurately check the remaining amount. have

In addition, if the blinking switch of the lamp and the power switch of the heating element are the same or connected in conjunction, the heating evaporation device is easy to use, as it is possible to check the remaining amount of the chemical solution at the same time as the chemical solution is heated and evaporated. can be provided.
